Supplies

Dollar store / gas station / Walmart flashlight. (Check that drawer in your kitchen, I had two)


Resistor depending on power supply and needs.

Some thin wire, something you can route in the unused rail slot behind the psu


Assembly

Disassemble the flashlight and remove the head
Solder wires to the head of the flashlight as shown below (fig1), the inner ring should be the cathod (+) and the outer ring should be the anode (-)
Pass the wires through the cap
Insert the bolt into the head, this also should be quite snug to prevent it from spinning, use the nut to draw in if needed
Fit the LEDs into the head
Press the cap into the head
Assemble the rest of the arms as shown below(fig 2)
Slide the assembly onto the rail
Wire as needed
Important: there is no resistor in the head of the flashlight be sure to add as needed depending on your power supply. See resources below

Resources

Ohms Law calculator if you need help calculating your resistor.

Example: to run this off the 5v power supply at 20 milliamps you would use a 160ohm resistor. (Assuming a 1.8v drop on the LED)

Check the wattage rating on your resistor
